Wildlife Monographs, EarlyView.We describe the host response continuum for highly pathogenic avian influenza viruses (HPAIV), including the continuum of host responses to HPAIV infection and exposure based on the primary axis of host competence, ability to infect other hosts, and host vulnerability.

In this paper we consider stochastic processes with an embedded Harris chain. The embedded Harris chain describes the dependence structure of the stochastic process.

Regret based Robust Solutions for Uncertain Markov Decision Processes
, 2013 In this paper, we seek robust policies for uncertain Markov Decision Processes (MDPs). Most robust optimization approaches for these problems have focussed on the computation of {\em maximin} policies which maximize the value corresponding to the worst ...

Digging into dirt: Rewilding with threatened mammals shapes soil‐emerging insect assemblages
Journal of Animal Ecology, EarlyView.By comparing insect communities across treatments at two time points, we show that reintroduced digging mammals shape soil‐emerging insect assemblages. This provides empirical evidence that restoring ecosystem engineers may drive broader community‐level change in semi‐arid ecosystems. Abstract Digging mammals function as ecosystem engineers by altering

On Markov Chains with Uncertain Data
In this paper, a general method is described to determine uncertainty intervals for performance measures of Markov chains given an uncertainty region for the parameters of the Markov chains.

Riding out the storm: Behavioural responses of a large herbivore to high‐Arctic winds
Journal of Animal Ecology, EarlyView.Using 11 years of GPS data from 61 muskoxen in Northeast Greenland, we show how increasing wind speed and Arctic storms reshape movement modes and habitat selection. Muskoxen respond by bedding in dense vegetation, prioritizing energy conservation over foraging, revealing a simple behavioural strategy with potential fitness consequences under ...

Real Estate Economics, EarlyView.Abstract We estimate the price impact of very nearby concurrently listed properties in the Sydney housing market and assess their competition effects. We apply a hedonic model with spatiotemporal effects regularized via a graph Laplacian prior at the month‐by‐SA2 regional level to seven SA4 subregions of metropolitan Sydney. The model structure enables

Long‐run confidence: Estimating uncertainty when using long‐run multipliers
American Journal of Political Science, EarlyView.Abstract Researchers are often interested in the long‐run relationship (LRR) between variables where the dependent variable has dynamic properties. Though determining the long‐run multiplier (LRM) for an independent variable is straightforward, correctly estimating the significance of the LRM is often difficult, especially when time series are short ...

Andrology, EarlyView.ABSTRACT Background Testicular cancer (TC) is the most common malignancy amongst adolescents and young adults (AYAs) aged 15–39 years assigned male at birth. Survivors often experience late effects of treatment and report unmet supportive care needs.

Simulation or cohort models? Continuous time simulation and discretized Markov models to estimate cost-effectiveness [PDF]
The choice of model design for decision analytic models in cost-effectiveness analysis has been the subject of discussion. The current work addresses this issue by noting that, when time is to be explicitly modelled, we need to represent phenomena ...
